This repository provides the MATLAB implementation and example dataset associated with the grain-shape based methodology proposed for reconstructing grain-scale plastic strain tensors from sequential EBSD maps. The approach estimates the in-plane strain tensor of individual grains by tracking invariant microstructural features (triple junctions) between an initial and a deformed configuration. Directional strains are determined from the change in radial vectors relative to grain centroids and the strain tensor components are identified through a least-squares formulation. The repository contains: • MATLAB scripts implementing the strain reconstruction workflow • Example EBSD datasets for commercially pure titanium (cp-Ti) • Functions for grain reconstruction, twin-related grain merging and strain computation • GROD analysis and correlation with equivalent strain The main script `run_cpTi_example.m` reproduces the complete workflow used in the study, including: 1. Loading EBSD maps2. Grain reconstruction using MTEX3. Twin-related grain merging4. Grain-scale strain tensor reconstruction5. GROD computation6. Statistical analysis and publication-quality figures This example dataset corresponds to plane compression of commercially pure titanium (ASTM Grade 2) with a macroscopic thickness reduction of approximately 12–13%. The repository is intended to provide a reproducible reference implementation for researchers interested in grain-scale plasticity analysis using EBSD. Requirements:• MATLAB• MTEX toolbox
